MOP 'WIRING-E3..

applicati@ mea api-i1 al new and useful Improvements in Mop Y Vringers; and li do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to` the accompanying drawings, and to thek reference numerals marked thereon, which form part of this specification.

My present invention relates to mop wringers of the form where'the mop is placed between two rollers whichl are rotated so as to move the mop lengthwise and at the same time pressed together so vas to force the water'from the mop. Y' The purpose of my invention is to pro! vide a mop wringer of the type described which is simple, light in weight and very rigid and adapted to exert great pressure upon the mop with a minimum Vof power applied to the device.

A further purpose isto provide an article of the class described wherein the Awringers are mounted onl the ends of two 'pairs of plvoted arms pro]ectmg towards each other from a rigid rectangular'frame at the top of the device and wherein great pressure mayy be obtained by toggle action particularly as the rolls arebrought close Atogether and almost in alignment with the pivoting points of the swinging arms. l

Another purpose is to provide `a -mop wringer wherein rigidity is secured by improved form of construction, but with light vness of the parts and of the device as a whole; further to provide a device where a minimum of motion of the treadle produces a maximum ofV pressure upon the wringer rollers; further' to so construct' the Vdevice Vthat friction is reduced to a minimum through having the moving points freely mounted whereby substantially all the power is exerted upon the mop and particularly' results in being able to utilize a relatively light tensioned spring to move the 1922. serial No. 54110-1.

. but which can be readily repaired or have parts thereof replaced.

Further purposes andadvantages of .my

invention will appear-from the specification and claims herein.

Referring to the drawings in-a more par ticular descriptionfit will be lseerrthat the .enlargedt scale on line 6%-6 o-f mop wringer comprises a platform 10 froml the opposite sides of which rise rigid' side frames the tops 'of' which are provided with side top pieces 11 theends of which are j connected by front and rear vtop piecesy 12 and 13 forming-a rigid rectangularframe at the top ofthe device within whichframe are swingingly mounted the frontand rear wringer rolls 14. and 15.

The sidefframes of the-device are corn-p-v posed of a long bar 16, a short bar -17 and an intermediate lengthed barv18. Thelong bar 16 has its lower end secured to the plat# form near its-'rear corner as by screw 19 while the said rod extends upwardly and forwardly in a. slanting direction an'dlhasl plece its upper end secured to the side to 11 vnear its forward end rigidly y the headed screw 20 and Anut 2l. The short -bar 17 has its lower end secured as by screw 22' to the side or edge of the plat-forninear its forward Vcornerwhile the upper end of said bar is rigidly connected to the lower end of the bar 18V as by bolt '23 and nut 524 ata point substantially directly above the lower end of bar 17. The bar 18 extends upwardly and rearwardly and `is rigidly'secured at its upper end tothe side top piece 11 near its rear-side as by headed lscrew 25' and nut 26.. Vhere the'bars 16 and 18 crossv they are rigidly connected as Vby bolt 27. It willnow be seen vthat eachv side frame Y i 7 0 Fig.- Ll is a verticalsectional view of'oneesv ` v including-as itdoes a side top piece V11 is a very rigid construction.

piece l1 as already described but aflo'rdr'the means of pivotallyV mounting the swingingV arms 28. rlhe said headed screws 2O and 25 have their heads on the inside of the'top rectangular frame and spaced along on the shank of the said screw a short distance from its head is a shoulder 29 taking against the inner surface ofthe side Vtop piece 1l and allowing the swinging arms 28 tobe mounted on the shank of the headed screw i as' aV pivot, but .without pressure or binding strain upon the said swinging arms'. The arms 28 are mounted in pairs on each side of the machine, each of the rear arms having a hole near its free end forming a bearing in which is mounted the stub shaft or pin 30 projecting from the oppositeY ends of the rear wringer roller 15. In a similar `way the two', forward swinging arms 28 supportthe stub shaftor pin 31 of the front wringer roll 14. e Y Y Loosely mounted upon Vthe said pins of the wringer rollers and'inside of the `swinging arms 28V are the upperends of the forward and rearward connecting rods 32 and Y33 respectively. The lower ends of the connecting rods on either side of the machine Y are broughttogether and pivotally connected as by bolts 34 to the l legs of the YU-shapedtreadle3. VVThe forward end of Vthe legs of this treadle areipivcted tothe Y forward Vpart ofthe side frames as by being Y mounted upon the bolts 23 on the inner side of the frame said bolts being provided with shoulders or other means to keep the head of the bolt from pressing against the treadle. Similarly the bolt 34 has a shoulder or other means spaced from its-head so as Ytofallow the lower ends of the connecting rods 32 and 33 to freely swing onsaidbolt.

4 On the outer part of thebolt 34 is Vpro-l vided a holder 36 like a grooved'pulley and a similar holder 37 is provided 'on the outer end ofthe boltV 27. Mounted upon these f holders and stretched between the holders on eachrside of the machine there is provided an endless coiled spring 38 of such Y strength asto hold the rollers and treadle and'V attached parts in upper or inoperative position whenno power is applied to the machine. rlihe swinging arms 28 are ofV The headed suchk length and-:the parts are so propor- Y tioned that as the foot is vplaced upon'the rearwardly extending peddle portion 39 of the treadle 35 the upper ends of the connecting rods 32 and V33 will draw the` wringer rollers down and towards each other on their swinging arms 28 forming aswill be seen from Fig. 1. a sort of togglev action which will bring the rollers withincreasingly greater pressure against 4thev mop as the rollers approach their lower po,- sition;

inoperative position vwhen the-foot is re As all the moving parts are rela- Y tively light and swing freely on good bearvings very little tension from the spring 38 is required to return the rollers tovupper or lY0 Y moved from the peddle. It follows from f this that while the'spring isplacedp under tension during the downward or working i stroke of the tieadle the slight power used therefor is not noticeable and is a great saving in labor over the vmop wringers re- 1 quiring greater 'tensionffor return of the.

parts to expanded position. Y

Upon the projecting pinpreferably of the forward roller there'is mounted a crankv 4l with handle 4:0 whereby inan obvious' manner the forward roller may he rotated. Preferably this forward roller is corrugated so that as the said roller isrotated clock-( wise as seen from the right-hand or handle'k end the mop will be positively grasped and forced upward in the desired manner.. ItY

Vwill be understood of course v,that in Ythis style of wringers'the upper part of th'eiwet Y mop isplaced between the 'wringer'rollers kand the mop moved upwardly forcing the"v water continuallyffurther down onrthe mop and allowing the water to fall' into thepail Y (not shown) upon the platform beneath the, wringer rollers.v v Y Y The heads of the screws 2O and 25" form y y inwardly Yextending stops to engage the connectingrods 32V and 33 respectively asthe Y '110 v forming a positive stop atthe upward Inove-V y, V

rollers come to separatedA 4position thus ment ofV the rollers and preventingftheir accidentally going past Vcenter relative to the force communicatedY to the rollers from the said connecting rods. Y

It will be noted that when the wringer 'rollers are forced downward and the greatest pressure exerted Vtherebythe strain' of such pressure is communicatedl back as athrust through the short swinging'arms 28 and then taken asa direct ypulling strainV upon the opposite ends of the top side pieces j 11 thus operating to vrelieve' the members of the `upright side frames from v .any Ppm? ciable strain from such pressure.
